Unformatted text preview: t is a scaling function, what about the corresponding wavelet? We again operate in the frequency domain to find the wavelet. By taking the Fourier transform to both sides of below equation we get equation (4), we have its frequency domain equivalent. For our ideal ( ) H Create PDF files without this message by purchasing novaPDF printer ( http://www.novapdf.com ) Which is an ideal HPF. Because of the association of the sinc function with sampling theory, the scaling function ( ) t is known as the Shannon scaling function, and the wavelet is known as the Shannon wavelet which is bandlimited.
